Generate new rails app project

Create a new app specifying the rails version & database.

$ rails _3.2.11_ new learnapt-web --database postgresql --skip-test-unit

Here's how to install PostgreSQL and have it run automatically at startup, on an Ubuntu 10.04 virtual machine using Vagrant. This took me a while to figure out:

Add the default lucid32 base box to your vagrant, if you haven't already:

host> vagrant box add lucid32 http://files.vagrantup.com/lucid32.box

Now make a new lucid32 virtual machine and install postgresql on it:

	##
	# Class description
	# goes here.
	class State < ActiveRecord::Base

	#-- attributes

	attr_accessor :id, :name, :slug, :country_id

	#-- validations

	public void loadUpdates(boolean loadWordADay)
	{
	try
	{
	if (Util.isNetworkAvailable(this))
	{
	sendProgress(ProgressMode.UPDATE_STARTED.ordinal());

	//-- Update Word of the day
	if(loadWordADay) {

	app.factory "User", ["$http","$resource",($http,$resource) ->

	User = $resource("/roles/:id", {id: "@id"}, {update: {method: "PUT"}})

	# Initialize the data using a static method
	User.init = (data) ->
	angular.extend this, data

	# a static method to retrieve User by ID
	User.get_it = (id) ->

	# Authenticate:

	curl -H 'Content-Type: application/json' \
	-H 'Accept: application/json' \
	-X POST http://localhost:3000/users/sign_in \
	-d "{'user' : { 'email' : '[email protected]', 'password' : 'password'}}" \
	-c cookie

	SELECT pg_terminate_backend(pg_stat_activity.procpid)

	WHERE pg_stat_activity.datname = 'TARGET_DB'
	AND procpid <> pg_backend_pid();
